Abstract

A circularly polarized flat lens antenna element is presented in this article. The element is designed by using aperture-coupled patches with a common ground plane. A pair of identical cross-shaped slots is loaded on the common ground plane to realize circular polarization (CP). The desired phase error compensation and axial ratio performance for CP are achieved by tuning the slots dimensions. The proposed element achieves a very good 3 dB axial ratio bandwidth of 21%, phase shift range of 225° and low transmission coefficient of only 1.9 dB.This element employs a simple and less fabrication complexity mechanism for polarization conversion.
